Speciation of copper in waste incineration fly ashes (dry scrubber (DS) and bag filter (BF)) has been studied by X-ray absorption near edge structural (XANES) spectroscopy in the present work. Copper species such as metallic Cu, CuO, Cu(OH)2, and a small amount of CuCO3 in the fly ashes could be distinguished by semi-quantitative analysis of the edge spectra. Interestingly, nano CuO (37%) were ...

Edge detection is one of the important preprocessing steps in image analysis. Edges characterize boundaries and edge detection is one of the most difficult tasks in image processing hence it is a problem of fundamental importance in image processing. Edges in images are areas with strong intensity contrasts and a jump in intensity from one pixel to the next can create major variation in the pic...

Edge detection is one of the most frequently used operations in image analysis. If the edges of images could be recognized accurately, all of the objects can be located efficiently and performance can be measured easily. It reduces the complexity of image processing algorithms by reducing the amount of data to be processed .The quality of image is affected when there is an jump in intensity fro...

Distinct spectral features at the Fe L-edge of the two compounds K3[Fe(CN)6] and K4[Fe(CN)6] have been identified and characterized as arising from contributions of the ligand pi orbitals due to metal-to-ligand back-bonding. In addition, the L-edge energy shifts and total intensities allow changes in the ligand field and effective nuclear charge to be determined. It is found that the ligand fie...

A edge 2-rainbow dominating function (E2RDF) of a graph G is a ‎function f from the edge set E(G) to the set of all subsets‎ ‎of the set {1,2} such that for any edge.......................

the evaluation of the edge effects of forest roads on ecosystem is very useful to understand changes from forest road. with this regard, in this research the effect of main forest road construction on regeneration and biodiversity of established trees in edge of forest road was investigated at 35 m distance into forest area. an existing 10 years old road segment, with same physiographic propert...

Edge detection is one of the important pre-processing steps in image analysis. Edges characterize boundaries and edge detection is one of the most difficult tasks in image processing hence it is a problem of fundamental importance in image processing. Edges in images are areas with strong intensity contrasts and a jump in intensity from one pixel to the next can create major variation in the pi...

We consider the problem of maintaining a large matching and a small vertex cover in a dynamically changing graph. Each update to the graph is either an edge deletion or an edge insertion. We give the first randomized data structure that simultaneously achieves a constant approximation factor and handles a sequence of K updates in K · polylog(n) time, where n is the number of vertices in the gra...

A CMOS PWM Transceiver is designed and implemented with the help of self referenced Edge Detection technique. The Transceiver is designed with out the use of Phase locked loop which occupies large area and large amount of Power supply. Edge detection technique contrast the difference between the rising edge and modulated falling edge. The modulated falling edge is delayed by 0.5T in one carrier...

We propose to use the combinatorial assignment problem to model the issue of associating ground-truth and declared edge pixels in the objective empirical performance evaluation of edge detectors. The assignment problem is adapted to the maximal assignment problem to incorporate the need for tolerating certain amount of localization error for the detected ground-truth pixels. The solution to thi...
